I bought this box to upgrade a Vista laptop for HTPC or DVB-C receiver with HDD / DVD recording function after my DVD / HDD recorder has given up the ghost. I run the box on the cable network of KabelBW and have no problems to receive all programs (the CI slot, I use not). The receipt of the cable signal is better than that of my pretty fashionable Sharp TV set. The device is only slightly warm even in continuous operation. This box runs with Windows XP / Vista / 7 (x64), but will not run in all probability with Windows 8, since the manufacturer reportedly out of business retreats with PC products and develops new drivers more (possibly could use one newer drivers a related product from a different manufacturer, but for that I have no information). So if you now use Windows 8 or want to change in the near future, should be informed. From the enclosed software I use only the driver. The included editing program is not just the latest in the market and was not even installed by me. Together with the DVBViewer program Pro (price 15 euros) and there also available Record Service I have now a very good DVB Receivers (for cutting the video files I use TS-Doctor), of the TV program or the recordings into LAN streaming. Without the DVBViewer Pro is the box quite usable (an OEM version of the DVBViewer with a significantly lower scope is included), but in my opinion makes it only with this outstanding program (actually a complete Media Center) and the extensions for available and Plugins really fun. I would give the box five stars were it not for the matter of the end of the PC business from the manufacturer and the uncertain future in terms of current drivers, etc. That is why a point deduction.
